A Word of Caution About Extensions

Safari is a fast and lightweight browser, but the more extensions you install the slower it will be. If you install a lot of extensions, the performance of your system will suffer.

You should consider how useful an extension will be before installing it. If you do install a lot of extensions, disable ones you’re not currently using (check out the Disabling or Uninstalling Safari Extensions section below).

Disabling or Uninstalling Safari Extensions

Safari extensions you don’t use anymore can be disabled or uninstalled. If you’re experiencing problems in Safari, you may want to disable all your extensions and then re-enable them one by one. This can help you determine if an extension is causing the problem, and which one. If you decide you don’t want an extension at all anymore, you can uninstall it.

Note: Closing all open tabs in Safari is recommended before disabling or uninstalling extensions. If you have a lot of tabs open, Safari’s performance worsens noticeably when you disable or uninstall an extension. Each open tab has to adjust to no longer having that extension active, especially when that tab was using the extension.

To disable or uninstall an extension go to Safari > Preferences, then click Extensions on the toolbar.

Uncheck an extension in the list on the left to disable it. To uninstall an extension, select it in the list, then click Uninstall on the right.
